CHARLES E. GOOGINS, OF BROOKLYN, NE YORK.

STEAM-BLOWER.

SPECIFICATION forming part of Letters Patent No. 784,488, dated March 7,1905.

Application filed May 20, 1904;. Serial No. 208,898-

To (all whmn it may concern:

Be it known that 1, CHARLES E. GooeINs, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Steam-Blowers,of whichthe following is a specification.

My invention relates to steam-blowers for ejecting air or noxious gasesfrom any inclosed space whether for ventilation or for other reasons,and it may be also employed to deliver a strong constant blast of air tofurnaces as forced draft or to be directed wherever desired for anyspecial purpose.

Contrivances having the general nature of my invention and fallingwithin the class to which it belongs create a moving current of air bymeans of one or more steam-jets passing through nipples having usuallycontracting and expanding mouths, the action of the jet being in part tocause a partial vacuum and consequent inrush of air into the contractingmouth which first receives the jet and to impress a portion of itsVelocity upon the air so taken up, the condensation of the steamcontinuously making room for more air entering the system in the samedirection with the jet.

Various combinations of mechanical parts have been constructed foradjusting the jets with respect to the nipples or injector-tubes and forlocating those parts with reference to the casing or pipe through whichthe blast is delivered.

The object of my invention is to provide in 'a steam-blower deviceshaving particular and improved form and arrangement whereby the jets andthe nipples are adjustable with regard to each other and to the blast ordelivery pipe.

1 accomplish the object stated by fashioning and assembling the parts asillustrated in the accompanying drawings, wherein- Figure 1 represents alongitudinal sectional view of the associated elements. Fig. 2 is a planview of the crank-ring. Fig. 3 is a plan view of the jet-frame. Fig. 4represents a cross-section upon the line 0 a of Fig. 1 looking towardthe blast-pipe and showing one of Fig. 5 is a vertical secthelocking-plates.

tion, and Fig. 6 a top view, of the clampingnuts which support thenipple-seating plates upon the screw-rods.

Like numbers are used to refer to like parts in all the views.

Each constituent element is described in detail and its individualoffice, together with the mode of operation of the whole, fully setforth herein.

Considering the drawings, numeral 1 designates a steam-pipe usuallyfurnished with a cut-otf valve 2, an escape-valve 3 for permittingescape of condensed steam when starting the blower, and a third valve 4to admit steam immediately to the jet-pipes As ordinarily constructed byme the jet-pipes consist of two parallel members and one mediantransverse member, all formed integrally with a cruciform frame 6. (SeeFig. 3.) The parallel members of the jet-pipes have jet-nozzles 7 attheir extremities, making four nozzles, and the transverse member of thejet-pipe possesses a nozzle at each end and in the middle, making atotal of seven nozzles T. The bores 8 of the nozzles expand slightlytoward their mouths, this being found to be the form of jet offeringleast retardation to the force of the steam. Smooth-bore bosses 9terminate the arms of the jet-frame 6, and at the middle of the frame isa suitable coupling 10 for the steam-pipe.

Number 11 marks the screw-rods extending lengthwise of the invention andby which the parts are held together and adjusted. Two of the four rodsare shown in Fig. 1. Each rod has an integral collar 12 near its upperend and a smooth cylindrical extremity 13, which passes through a boss 9of the jet-frame and is provided with a crank 14. Three of the crankslet have at their outermost ends the smooth pins 15, provided withthreaded ends. The pins 15 pass movably through smooth holes bored atquadrantal points through the crank-rii'ig 16, and nuts 17 engage thethreaded ends of the pins and retain the crank-ring. (See Fig. 2.) Oneof the pins 14 is extended into a handle 18, and as all the cranks areconnected by the ring and have the same throw all are turned by means ofhandle 18. It is thought to be now apparent that when p 22 are taken offthe ends of 'the sleeve-nuts,

which are then passed through suitable openings near the edges of theplates 24, whereupon the nuts 22 are again screwed into position and theplates supported between them and the shoulders 20 of the sleeve-nuts.The nuts 19 are freely movable and revolublein the openings of plates24, through which they pass. It is found to be desirable to lock theclamping nuts after the plates have been placed in position. 1 effectthis by constructing the annular lock-plates 25. (See Fig. 4.) Thelock-plates are movably held upon the surfaces of the plates 24 by theheaded pins or-screws 26 passing through curved slots 27 of thelock-plates into plates 24. To engage the nut-form ends 23 of thesleeve-nuts 19, and thus to prevent the nuts from rotating withrespectto plates 24, slots 28 are formed through the lock-plates, havinga circumferential direction, and enlarged portions 29, contracting intoportions of less width and having parallel sides 30. It will be notednow that if a lock-plate be moved by means of its handle 31, causing theparallel sides 30 of the slots to engage opposite and parallel sides ofthe tops 23 of nuts 19, the nuts cannot thereafter turn with respect tothe lock-plate or nipple-seating plate '24. The remaining ends of thescrew-rods 11 pass through the flange 32 of the blast-pipe 33, as shownin Fig. 1, and nuts 34 secure the rods to the flange.

All similar parts are duplicates excepting the nipples orinjector-tubes. Considering Fig. 1, the upper nipples 35 (those nearestthe nozzles-7) are the smaller in size, while nipples 36 (shown in thelower position) are larger. The first set of nipples directs the jetinto the second, and between them the way is open -to entering air,drawn in mechanically by the friction of the jet with surrounding airparticles or pressed in to fill the place occupied previously bycondensed steam. Air is thus taken up in the stream and. forced forwardby the steam through the longer nipples 36 into the blast-pipe 33,having the contracted entrance shown, and by the combined action of itsvelocity and the further condensation of the steam a strong blast of airis delivered through pipe 33, of which the condensed steam constitutes asmall part volumetrically. The nipples are held in the plates 24 by theengagement of relatively enlarged The office of cylindrical portions 37and shoulders 38 with suitable seats or orifices 39, formed through theplates.

The operation may be described as follows: Vhen the parts have beenassembled, as illustrated in Fig. 1,with the clamping-nuts locked andnuts 34 unscrewed, the screw-rods may be turned by handle 18 and ring 16and all the nipples, both large and small, moved together toward or fromthe jet-pipes or blastpipe; but if one of the lock-plates is turned,bringing the greater openings 29 of its slots 28 about the ends 23 ofthe sleeve-nuts, those nuts will turn by reason of frictional engagementwith the screw-rods and will not change positions along the rod. Theremaining lockplate upon the other nipple-seating plate prevents its setof nuts from turning, and therefore these non-rotating nuts, with plate24 and nipples borne by it, will be moved toward or from the other setof nipples.

Having thus described my invention and explained the manner of itsoperation, what I claim is 1. In a steam-blower, the combination with amovable blast-pipe, of a jet-frame and jetpipes provided with nozzles,means for serving steam to said jet-pipes, a movable nippleseatingplate, nipples seated upon said plate and supported thereby in alinementwith the said nozzles, and adjusting devices whereby the said plate andnipples and the said blastpipe may be adjusted toward or from saidnozzles and with respect to each other.

2. In a steam-blower, the combination with a movable blast-pipe, of ajet-frame and jetpipes provided with nozzles, means for serving steam tosaid jet-pipes, a movable nipple-seating plate, nipples seated upon saidplate and supported thereby in alinement with the said nozzles,adjusting devices whereby the said movable plate and nipples and thesaid movable blast-pipe may be adjusted toward or from said nozzles andwith respect to each other, and locking means adapted to place one IIOof said movable elements in and out of engagement withsaid adjustingdevices.

3. In asteam-blower, the combination with a blast-pipe, of a jet-frameand jet-pipes provided with nozzles, means for serving steam to saidjet-pipes, movable nipple-seating nuts, and movable annular lockingrings borne by said plates and havmg slots arranged to engage said tops23 of the nuts whereby the I 5 revolution of the clamping-nuts ispermitted and prevented and said plates adjusted.

In testimony whereof I affix my signature in presence of two witnesses.
